Note: For VS <2015, the following works only for the VB.NET code editor. In VS 2015+, apparently the C# code editor is also supported.
While there are no default keyboard bindings to jump between methods, you can set them up yourself:
Go to Tools → Customize…, then Keyboard…, and do the following:
-
Search for the commands by typing
Methodin the input line at the top. -
Locate the two commands
Edit.NextMethodandEdit.PreviousMethod. -
For each of these, select the command first, then move the input focus to the input field Press shortcut keys, enter an unassigned key combination, and press the Assign button.

(The screenshot above shows that I have previously assigned one of these commands to Ctrl+Shift+<.)
